I haven't been writing for the blog lately, but I have been writing.
Mark Mather and I, along with the team at PRB, published a new report on the state of young women's well-being in the U.S. across four generations?
The news?
Not so great for Millennials.
There has been progress in some areas (rising educational attainment, falling rates of cigarette smoking and homicide) but dramatic reversals in others (rising rates of incarceration, poverty, suicide, and maternal mortality).

Demographic trends in San Diego County – new data from Census 2010
Population Growth 1910-2010
In the past 100 years, San Diego county has grown from a small city of 60,000 people to a thriving metropolitan area of more than 3 million. In San Diego’s early years Census figures show that the county’s population nearly doubled every ten years from 1910 to 1960. Between 1960 and 1990 growth slowed to an average increase of approximately 33 percent every decade. Growth slowed again in recent years, with less than a 15 percent increase 1990-2000 and only 10 percent growth from 2000-2010.
Migration Patterns
Migration was the primary driver of population growth at the beginning of the last century, but that trend has shifted considerably in recent decades. Until the late 1990s, most growth in Southern California was a result of in-migration from other parts of the United States and from other countries around the world.
However, according to data from the U.S. Census Bureau American Community Survey and a study by the University of Southern California Population Dynamics Research Group, that trend has shifted statewide, with most of the population now being, in the words of the study authors, “homegrown” (i.e. born in California).
Aging Population
As San Diego grows, it is growing older. The very first trickle in the aging wave of the Baby Boomers just turned 65 this past January. Because the Baby Boom is just now reaching this milestone, the proportion of the population age 65 and older had remained constant at 11 percent over the past two decades. However, that will shift dramatically in the next two decades.
On the younger end of the spectrum, the share of San Diego's population under the age of 18 is shrinking, from 26 percent in 2000 to 23 percent in 2010. As a result of these shifts the median age (the point at which half of the population is younger and half older) increased from 31.0 years in 1990 to 34.6 today.
Race and Ethnicity
One of the biggest demographic shifts highlighted by the 2010 Census is confirmation that San Diego is now a “majority-minority” county. This means that no single race or ethnic group accounts for more than half of the region’s population.
The Asian population, which grew fastest, increased by 34 percent (to 328,000 residents) between 2000 and 2010. The Hispanic/Latino population increased by 32 percent over the decade, and now accounts for approximately one third of the county’s total population (991,000 residents).
Conversely, the non-Hispanic White, Black, and American Indian populations all declined slightly during the decade (by 3, 5, and 8 percent, respectively)
Housing - Occupancy and Household Size
While much talk about the Census revolves around the demographic characteristics of the population, the 2010 Census also provides valuable information about neighborhood housing characteristics including occupancy rates and average household size.
In 1950, the average household size in San Diego was more than 3.1 persons per household. This decreased steadily as birth rates and average family size fell during the 1960s and 1970s, so by 1980, the region hit a low of 2.6 persons per household. However, birth rates began to rise starting in the mid-1970s, and a similar upward trend can be seen in average household size.
San Diego's lowest residential vacancy rates, not surprisingly, were during the housing boom in the early 2000s, and have risen considerably – back to rates reminiscent of the 1970s and 1980s – in the past three years. Data from the 2010 Census shows a residential vacancy rate of 6.7 percent for San Diego county.
2010 and Beyond
The demographic characteristics of the San Diego county will continue to evolve over time. San Diego is transitioning from a history of high-volume in-migration, to a more “homegrown” population, and from a relatively "young" area to a metropolitan area with an aging population.

Aging population and driving
This story in today's San Diego Union Tribune, about a fatal accident involving a 71-year-old driver, prompted me to post a piece I've been working on for a couple of weeks...
Six months ago the first wave of Baby Boomers turned 65, prompting questions about how the nation's transportation system will adapt to an aging population. There are some benefits that may arise from having an older population, and there will undoubtedly be challenges.
As the population ages we may care less about our cars. A Gallup poll in 1991 found that 20 percent of Americans found driving to be a chore. The same response in 2006 got a 40 percent boost to 28 percent. When you drill down into the details of the survey, likelihood of taking a ride “just because it’s fun” decreases substantially with age. In short, an older population is less likely to enjoy driving.
And, contrary to most road-rage induced stereotypes, older Americans also drive more safely. (However, there are some limitations to that trend, as described below.)
In their 2009 study of aggressive driving behavior, AAA found that at age 16 nearly 60 percent of drivers show aggressive behavior. By age 35 aggressive driving falls to 35 percent and by age 60 is below 27 percent.
With an already aging population, safer driving is beginning to show up in accident statistics. According to the U.S. Department of Transportation:
“in 2010 the number of traffic fatalities in America fell to the lowest levels since 1949...despite a sharp increase in the number of miles Americans drove last year - 21 billion additional miles. In addition, the rate of road fatalities in the U.S. has also dropped to its lowest level since 1949. Over the last five years, traffic deaths have declined by 25 percent…And the rate of fatalities per million miles traveled fell to 1.09 from 1.13 in 2009.”
Transportation Secretary Ray LaHood credits this to “the combined efforts of DOT, states, law enforcement, safety organizations, and America's drivers who are taking personal responsibility for their driving habits.” But I also see a demographic shift at play, much as there was a demographic influence on falling crime rates, beginning in the mid-1990s.
However, as opening article implies, there are also substantial health issues that may impair the driving of older Americans.
For example, the likelihood of reporting some form of disability DOUBLES between the age groups 65-74 and 75 and older (from 25 percent at age 65 to fully half the population age 75+). Similarly, according to data from the U.S. Centers for Disease Control and Prevention 10 percent of older men and 15 percent of older women reported cutting back on driving due to a physical problem in the past year. And, for a combination of reasons, older drivers are likely to avoid driving in certain conditions. Older drivers tend to avoid driving at night, driving in bad weather, and (to a lesser extent) driving in heavy traffic.
All of this adds up to some very complicated issues facing the nation's transportation system. Fortunately, research is underway to better understand the implications of age-related health issues on transportation at institutes such as the Age Lab at MIT.

Transportation by generation
Yesterday I participated in a demographics forum at the U.S. Department of Transportation to discuss the issues of an aging population on transportation infrastructure and generational differences in transportation use. The video and slides from the forum have been posted by the DOT.
